Grain simulates film grain with control of size, intensity and softness. In addition, a Film Response parameter controls where you will see grain in the image. Popular film stock presets are provided as a starting point to adding grain.

To select a preset, choose one from the Presets tab.

When enabled, the grain is monochrome. In this mode, parameters that have no effect are grayed out.

The Size parameter controls the size of the grain. The larger the Size setting, the larger the grain will be.

The Amount parameters set the red, green and blue intensities of the grain. Film stocks generally have varying amounts of red, green and blue intensities with the blue intensity generally higher than the rest. If you set the red, green and blue amount to a value of 0, the grain will disappear.

Controls the intensity of the red grain.

Controls the intensity of the green grain.

Controls the intensity of the blue grain.

The Softness parameter controls the softness of the grain. Normally, only minor softness adjustments are necessary, usually between a value of 0-1.

The Film Response parameters control where you will see grain in the image. In most cases, film grain is apparent over the entire image except the brightest whites with the black areas being the most affected.

Position defines the portions of the image where grain will be added. A low Position value places grain in the darkest image values, while a high Position value places grain in the brightest areas.

Increases or decreases the area where grain is added to the image based on the Position value. A low Range value indicates a narrow range of values, while a high Range value indicates a large range of values.

Sets the minimum level of grain that is always added to the image.
